Antique Bar-Limb Microscope

Circa 1850

Fine example of a mid 19th Century brass microscope in a fitted wooden case, complete with an eyepiece lens, objective lens and a live box. The microscope is made of lacquered brass. It tilts, has a rack and pinion main focus and additional fine focus on the back of the main tube. It has a square brass stage with a manually adjustable slide rest and two slide clips. Below the stage is a large adjustable mirror and a revolving plate for narrowing the field of light. There is also an additional holder with a further light filter which may act as a polariser. 

The microscope is unsigned with no indication of a maker but the craftsmanship is superb. The brass objective lens is marked 1/6in 0.87 N.A and has two stackable lenses to alter the strength and comes with a brass lens holder. The microscope also comes with a good quality eyepiece lens. 

The microscope appears to be in good working order and I have set it up and tested it with a few old slides (see photo). I'm sure the lenses would probably benefit from a clean but they produce a clear and bright image all the same and the microscope was easy to focus.

It comes in its original fitted case with sections to hold the lenses and eyepiece tube. There is also a pull out tray for holding slides and a section in the side for holding the live box. The box is good quality with a brass carrying handle and a nice aged patina and it comes with its original working key. There has been a small repair to the pull out drawer and there are some general signs of age and light marks on the box and a small split in the back panel but overall it displays very nicely.

The microscope measures approximately 13" tall when not extended. The box is a compact 10" high X 7" wide X 6" deep. 

The microscope is in good condition for its age and the brass has been lightly cleaned and polished. It has been well used and will have normal signs of wear so please don't expect it to be like new. There are areas of tarnishing where it has been handled are some small knocks and light scratches on the base but nothing detrimental. The lenses have small specks of dirt on and although in working order it is really being sold as a decorative / collectors item rather than an accurate scientific instrument.

The best description comes from the photos so please look at them all carefully and if you have any questions at all please ask.
